Applicatiofi filed April 27, 1911. Serial No. 623,665.

To aZZ whom it may concern:

Be it known that I, ELvIN EAST, a citizen of the United States, residing at Sheffield, in the county of Colbert and State of Alabama, have invented certain new and, useful Improvement in Spring vvheels, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to spring wheels and the principal object of the same is to provide a wheel which will have the same resiliency as a wheel provided with a pneumatic tire. I

The second object of the invention is to so construct the parts of the wheel that they will be dust proof, it being particularly desirous to provide the opening through which the spoke enters the hub with a device toprevent dust from entering the same.

Another object of the invention is to provide the outer ends of the spokes with braces which will prevent the spokes from having any pivotal movement.

This invention is illustrated in the accompanying drawings, wherein Figure l is a fragmentary view of a spring wheel constructed in accordance with this invention. Fig. is a sectional view through a portion of the improved wheel. Fig. 3 is a perspective view of one of the collars which is mounted upon the spokes. Fig. 4 is a perspective view of the outer end of one of the spokes.

This wheel comprises a hub 1, which is provided with an enlarged central portion 2. This central portiom2 is provided with an annular-1y extending groove 3 injthe inner edge of which there is provided a number of equally spaced circular socets l. The enlarged portion 2 is provided ith a transverse opening 5 positioned to pass through the central portion of each of the sockets 4-. These transverse openings 5 each have one end 6 threaded as shown in Fig. .2 for the reception of a pivot pin 7, which passes through the opening and is threaded into the threaded end of the openm The spokes each comprise an inner secprovided with an enlarged circular pivot one of the sockets A, and is held in place by the pin 7. A sealing member 10 is positioned to each side of the spokes and is pivotal'ly mounted between the walls of the end 9 which is seated within groove 3. These sealing members are held in contact with the spoke by means of springs 11 which are positioned between the sealing members and hold the same in place.

A band 12 which is provided with the openings 13 is placed upon the central portion 2 of the hub with the spokes passing through the openings 13, and is, held in place by the screws 14.. From an inspec. tion of Fig. 1, it will be readily seen that these sealing members completely close the openings 13 to each side of the spokes, and while they permit the spokes to have a certain amount of pivotal movement they; do not leave any opening through which. dust can enter the groove wheel to work badly.

A dust sleeve 15 is provided with a thickened inner end 16 which is threaded upon,

the threaded portion 17 of the inner portion of each spoke. the sleeve 15 intermediate its length, a nd is provided with oppositely disposed lugs 1,9

which are provided with sockets 20. The braces 21 are provided withscrew-eyes 22 3, and, thus cause thei A collar 18 is threaded upon which are threaded into openings 23, forttped in the hub 1 and have theirother ends nserted-within the sockets and are helef in place by means of the securing pins 24. which pass through the pin holes 25 formed through the lugs 19.

A hollow outer spoke section 26 is mounted upon each of the inner spoke sections 8 and passes between the spoke section 8 and the dust sleeve 15. A coil spring 27 is positioned within the outer spoke 26, and has one end secured to the end of the spoke section 8.

The outer end of eacli of the spoke sections 26 is provided with an enlarged sleeve 28 which fits within a socket 29 formed in the rim 30 or" the wheel and is held in place by" a i pin 81 which passes transversely through the rim and has its threaded end 32 secured in the rim. The rim is provided with a pair of pivotally mounted spring held lugs 33 which engage the spoke from each side of the socket 29 and brace the spoke. section 26 so as to limit the pivotal movement of the spoke in the socket. 34 of any desired material is the rim. I

After this device has been assembled the outer spoke sections have a. free movement between the inner spoke section 8 and the sleeve 15, so that any jar can be taken up A tire l "m umount G1. pwm L0 min but the 1 mg 13 {lapgsr 01f; dust u 11 mg the wheel.
